Plot

By accident, Heung Fan Shuk visits a magical website that lets its visitors barter anything they own in exchange for anything they want. Here, you can barter your slender waist for a place at an exclusive school for your younger brother or exchange your luck for a lover for your dear friend. Heung is hooked almost immediately. Later on when she suspects that her husband, Koo Ka Yan,, has a woman outside, she visits the website again to exchange her identity with that of her good friend Hou Yurk Hoi, who has married into a wealthy family. Heung hopes that Hoi can help her win back her husband's love. Hoi hopes that Heung can teach her overbearing mother-in-law, Lui Wong, a good lesson. Neither of them has thought that they will become hopelessly addicted to their new identity. By the time they realize how dangerous it will be if they carry on, the magical website has already been removed. The two families get entangled with each other as a result. Ironically, Heung has an affair with Yan! From then on, every day is filled with both laughter and anger for the two families.
